Abstract
The utility model discloses a textbook placement support bracket for mathematics teaching and relates to the technical field of teaching auxiliary aids. The textbook placement support bracket for mathematics teaching comprises an L-shaped supporting plate (1), a connecting plate (2), a sucker (3), U-shaped brackets (4), sliding sleeves (5) and an elastic band (6) and is characterized in that the connecting plate (2) is fixed at the middle part of the upper end of the L-shaped supporting plate (1); the bottom surface of the upper end of the connecting plate (2) is rotationally connected with the sucker (3); the end faces of both left and right ends of the L-shaped supporting plate (1) are respectively and fixedly connected with the symmetrical U-shaped brackets (4); the symmetrical sliding sleeves (5) are respectively arranged on the upper surfaces of the two U-shaped brackets (4); and the elastic band (6) is connected between the two sliding sleeves (5). The textbook placement support bracket for mathematics teaching has a simple structure, is convenient to use, can be used for effectively supporting and fixing a textbook and is convenient for a teacher to draw or write with more energy; and not only is labor intensity of the teacher reduced, but also teaching efficiency of the teacher is improved.
Description
Technical field: the utility model relates to teaching appurtenance technical field, and specifically a kind of mathematical education is placed Support bracket with textbook.
Background technology: in the mathematical education classroom, need teacher on the blackboard of being everlasting, to write formula and drawing, teacher is placed on textbook on the lectern usually when drawing, picking up drawing instrument then draws at blackboard, will constantly turn round the content of later checking on the textbook in drawing course, troublesome poeration is wasted time and energy like this, it is tired that teacher feels easily, brings very big inconvenience to teaching.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, easy to use, can effectively support and fix textbook, be convenient to the mathematical education that teacher writes formula or drawing at blackboard and place Support bracket with textbook.
The purpose of this utility model is achieved in that this mathematical education comprises " L " shape gripper shoe, connecting plate, sucker, " U " shape support, sliding sleeve, elastic webbing with textbook placement Support bracket, " L " shape gripper shoe upper center is being fixed connecting plate, bottom surface, the connecting plate upper end sucker that is being rotationally connected; Fixedly connected symmetrical " U " shape support respectively on the end face of two ends, " L " shape gripper shoe left and right sides is respectively equipped with symmetrical sliding sleeve above two " U " shape supports, is connected with elastic webbing between two sliding sleeves.
During use, at first by sucker this device is absorbed and fixed on the blackboard, and then textbook is placed on " L " shape gripper shoe and gets final product the page clamp of opening is fixing with elastic webbing, elastic webbing can move up and down in company with sliding sleeve as required.
Advantage of the present utility model: simple in structure, easy to use, can effectively support and fix textbook, being convenient to teacher has more energy to go to draw or write, and has both alleviated teacher's labour intensity, has improved teacher's efficiency of teaching again.
Description of drawings: Fig. 1 is structure chart of the present utility model.
The specific embodiment: describe in further detail below in conjunction with the utility model of Fig. 1: this mathematical education is placed Support bracket with textbook and is comprised " L " shape gripper shoe 1, connecting plate 2, sucker 3, " U " shape support 4, sliding sleeve 5, elastic webbing 6, " L " shape gripper shoe 1 upper center is being fixed connecting plate 2, bottom surface, the connecting plate 2 upper end sucker 3 that is being rotationally connected; On the end face of two ends, " L " shape gripper shoe 1 left and right sides respectively fixedly connected being respectively equipped with between 5, two sliding sleeves 5 of symmetrical sliding sleeve above symmetrical 4, two " U " shapes of " U " shape support support 4 be connected with elastic webbing 6.
